I get what you mean and how that works...but in my area, Ive never seen the cops use "tricks" to catch people. They basically just set up on the side or around a curve or something. As far as the "other" sources giving false readings but cops may be there, the Escort has a learning function which allows it to store and learn duplicate signals from doors, security systems, etc, and stores them. It will not give a false alarm on subsequent passes by. If a cop is hiding out there, it will register as a "new" signal and beep. I also like the GPS feature of the 9500 that allows it to display the speed youre going when it beeps. It also protects against the red light cameras and stationary radars...it knows where they are located.
Bottom line, they are about the same price...I was looking to spend under $250, but I like the expensive ones features of downloading updates..which is on either one of these. I wont make this a "which is better" argument, I just like the features and display of the 9500. I found a seller on Ebay (Top rated) that has them for $439..
Thanks for all the input.
